+   *
+   * So the code below is trying to detect if we are in the stub
+   * ("shr1" stub), and if so, find the real code ("shr1" trampoline),
+   * and if found,  do the symbolization from the real-code address
+   * rather than the stub address.

+   * Assumptions being made about the minimal symbol table:
+   *   1. lookup_minimal_symbol_by_pc() will return a trampoline only
+   *      if we're really in the trampoline. If we're beyond it (say
+   *      we're in "foo" in the above example), it'll have a closer 
+   *      symbol (the "foo" text symbol for example) and will not
+   *      return the trampoline.
+   *   2. lookup_minimal_symbol_text() will find a real text symbol
+   *      corresponding to the trampoline, and whose address will
+   *      be different than the trampoline address. I put in a sanity

+  /* FIXME: The native HP 9000/700 compiler has a bug which appears
+     when optimizing this file with target i960-vxworks.  I haven't
+     been able to construct a simple test case.  The problem is that
+     in the second call to SKIP_PROLOGUE below, the compiler somehow
+     does not realize that the statement val = find_pc_line (...) will
+     change the values of the fields of val.  It extracts the elements
+     into registers at the top of the block, and does not update the
+     registers after the call to find_pc_line.  You can check this by
+     inserting a printf at the end of find_pc_line to show what values
+     it is returning for val.pc and val.end and another printf after
+     the call to see what values the function actually got (remember,
+     this is compiling with cc -O, with this patch removed).  You can
+     also examine the assembly listing: search for the second call to
+     skip_prologue; the LDO statement before the next call to
+     find_pc_line loads the address of the structure which
+     find_pc_line will return; if there is a LDW just before the LDO,
+     which fetches an element of the structure, then the compiler
+     still has the bug.
+
+     Setting val to volatile avoids the problem.  We must undef
+     volatile, because the HPPA native compiler does not define
+     __STDC__, although it does understand volatile, and so volatile
+     will have been defined away in defs.h.  */
